[Mg-t] Fouled Spark Plugs

[S Allen]

Take the cap off, grab the dizzy shaft and give it a shake.  
If it moves it's
time for a re-build.

The case it pot metal, which over time will have an oval pattern on it when it
turns which will cause the back two cylinders to burn cooler.

Sometimes a Petronix ignition can fix the problem.

It seems that as long as I've had my '53 TD the spark plugs have fouled on a
regular basis. Last summer I had the carbs professionally rebuilt and adjusted
and expected that to solve the problem. But today I tried to drive the car and
it was running so rough I turned right around and went home.

I pulled the plugs and found #3 fouled (black material between points) and #4
somewhat caked with black material but not fouled. #1 and #2 were black but
not so bad looking. This is pretty much the same thing I used to see before
the carbs were rebuilt.

Carbs were rebuilt last September, 1300 miles ago.
Plugs were new last September, 1200 miles ago.
Ignition wires were new in 2007.
Distributor cap, etc. new in 2004.

So I'm wondering what I can do to reduce this fouling? Would hotter spark
plugs work; I'm currently using Champion L82YC. Would a sport coil help
(hotter spark)? And if so, I believe the plugs have to be regapped; to what
setting? Currently they are gapped between .020 and .022 according to the
book.

Thanks for any help.
